Oak Brook was originally known as Fullersburg, named after Ben Fuller, an early settler.

Oak Brook was incorporated as a village in 1958, due in large part to the efforts of Paul Butler, a prominent civic leader and landowner whose father had first moved to the vicinity in 1898 and opened a dairy farm shortly thereafter. Prior to incorporation, the name Oak Brook was used by local residents to distinguish their community from neighboring Hinsdale and Elmhurst, going back to the founding of the Oak Brook Civic Association almost two decades earlier.

The original boundaries were smaller than the present extent of the village, but a considerable amount of land was annexed soon after the founding of the village, including the land that is now the site of the Oakbrook Center shopping mall, which opened in 1962.

Paul Butler's interest in sport was reflected in the Oak Brook Sports Core, which features polo fields, a golf course (which was at one time the venue for the Western Open), swimming and tennis facilities, and other recreational facilities not commonly found in a village of this size.

The Oak Brook Historical Society was established in 1975 to serve as a community advocate for the historic preservation of the village and to be a resource for research and preservation of its history. Their current goal is to restore the Old Butler School, which will serve the community as the Oak Brook Heritage Center, operated by the Oak Brook Historical Society. The Heritage Center will provide multigenerational programming, exhibits of the heritage and history of Oak Brook, a research library, and small group meeting space.
